/**
* This class manages appearance options.
* There are two types of options: appearance and meaning.
* Appearance options affect the way that the design is presented to the user.
* Examples are grid dot spacing, layer stipple patterns, etc.
* Meaning options affect the way that a design is produced (for fabrication,
* simulation, and other outputs). Examples are CIF layer names, technology
* options, etc.)
* Meaning options are managed by Setting class now.
*
* Some Prefs can be used in server Jobs, other are client only.
* Server Prefs are created by special factory methods during Electric initialization.
* They can't be created later.
*
* All options are saved in a machine-specific way by the Java Preferences class.
* In addition, "meaning" options are stored in libraries. When the libraries
* are read back into Electric, the stored meaning options are checked against
* the current meaning options, the two are reconciled.
*
* Where are these options stored? It varies with each operating system.
*
* - Windows:
* In the registry.
* Look in: HKEY_CURRENT_USER / Software / JavaSoft / Prefs / com / sun / electric.
*
* - UNIX/Linux:
* In your home directory.
* Look in: ~/.java/.userPrefs/com/sun/electric
*
* - Macintosh System 10:
* In your home directory, under Library/Preferences.
* Look at: ~/Library/Preferences/com.sun.electric.plist
